'of New York. bave invented certain new and useful improvements in T ype-lVriting Machines= ot' which the following is a specilication.

This inrention relates to paper-guiding devices for the platcns of typewriting inachines, the, principal object being to enable the operator to write conveniently on small labels, cards, etc., and more particularly to enable him to cover the entire. label with writing, and also to enable him to see the entire line of writing, as itprogresses.

I employ a pair of transparent paperguiding ingerson opposite sides of and close to the printing point. said fingers being yieldinglv urged against the paper to hold it against the platen. the. type striking between said fingers. The platen and paper are slidable longitudinally. while the. paper holding fingers remain stationary. Said tingers are also shittable with the platen and paper for upper and lower case positions, so that the paper will always bc engaged by them.

ln the accompanying drawi1igs.l*`igure 1 is a perspective View, showing one embodiment ot' in v invention applied to the Underwood tijpe of front strike writing machine. Fig. .2 is a detail rear View, part-ly broken away to show the construction. Fig. 3 is an edge view, partly in cross-section, showing the platen in normal position to print lower case. characters. Fig. 4 is a similar View, showing the platen and paper-holding mechauism shifted to permit the imprint, of npper. case characters.

The frame A ot theft-ypewriter is provided 'with a cross-bar 1, to which is secured a typebar segment 2, in which the type bars 3 carrying the upper and lower case type T are pivoted. A platen -l is rotatably mounted in a platenraine 6, and lies in the path of the type 7.' the platen frame being provided with thefusual paper-feeding rolls 8 engaging the under surface. ot' tbs, platen 4. said platen and platen frame being sbitt-- able up anddown by a rocking frame including a pair of elbow levers S connected by a shifting rail 10, whereon rides a Wheel .11 of the'platen frame 6.

The rocking frame is swung from the position shown in Fig. 3, to that shown in Fig. 4. b i' depressing a shift key lever 12 fuit-ruined at 13,'wbicb lever operates an arln 14 engaging the rocking frame to etlect the cases-hitting movement ot the platen, whereby to etl'eetthe writing ot upper or lower case characters as desired.

A ribbdn vibrator l5 is interposed between the type T and the platen l, and includes a vertically slidable post 16. A viliraiug lever 1T fulerruied toa fixture 1S projet-ting from the shifting rail 10 has one end connected to the vibrator post. 16. the opposite end of the lever 1T, carrying a stud 19 receivable in a slotted arm 20 mounted on a table Q1, horizontally reeiproeable to vibrate the ribbon into the path of the type T as the latter is brought to the printing point.

The paper-holding mechanism includes a. carrier Q2. preferably,mounted to slide rertieallv, in the cross bar 1 of the franie ol' the I machine behind the segment Q, on which carrier are mounted upwardbv projecting arnis 9.3. whose free ends ha re secured thereto. paper-holding and guiding fingers '24.

preferably ot horn. Celluloid or other iransi parent niatcriai, and located on opposite sides ot the printing point, between the ribbon vibrator and the platen. the fingers being spaced apartV troni each other sailieiently to allow tbc type 'T to strike the label held therel against tbe'platen. The arms are preferably metallic, and (being opaque) terminate below the printing line. so as not ,i

to obscure the writing. the transparent fingers being secured to the upper ends of such arms at points below the printing line.' i

Those portions ot' the lingers which engage the label are smooth to oppose no resistance to the letter-spaeing travel ot the platen and label. tbe latter shifting relative. to the lingers. which. while holding tbe label against the platen, do notpress so tightly 10U as' to overcome its frietional adhereneeto` the platen, but rallier. maintain such adherenee in tbe line-spacing as well as in the L letter-spacing throw of the platen. Y The entire ,surface of'the label canv be 'los utilized for printing. Every portion of the. label along the printing line is in sight,

owing to the use of transparent paper-hold-l ing lingers Q4.

When printing `af-label. the latter is ingr Y 982,657

svrtvd downwardly in front of the platen l prnjvvting from the carrier t6, the free l end nl' tbv tongue loosely received in an eye l 't en thv shitting rail i0-, so that the opera` i tion ot the shift ltvv lever 12 to shift the platen t from lower to upper :e position or vive versa will came thtl slziitiugfy rail 1t) to .slide the carrier QQ, and the paper-holdl in;r finger 23 mounted thereon. vertically. up nr down. sinniltanvouslv with the platen, the. paper-holding devices hence occupying the saine relation te the platen in either its upper or lower case. positions.

The carrier 29. may he provided with shoulders 2T to engage the cross-har l and segment i* to arrest the carrier when the platen lrops to lower-vase position. The! carrier may he also he provided with open seats 25, tr; rvmovahl) receive pintles 29 carried b v the lower ends of the arms Q3. whereby the latter are detachahl)7 hinged to the carrier, to permit their removal if desired when the operator is writing on sheets of ordinary size which can he held by the usual parer lingers. y

Arms 23 and fingers Q-t are urged toward the platen preferably by leaf Springs 30 mounted on and e.;tenrlin r longitudinally of the respective arms 23, the. lower free ends of the springs BO havingl heads or detents 3l received in recesses 32 formed etcriorl.7 of the seats '2S to lock the arms and fingers yieldinglv to the carrier 2Q. the springsl being separated from the arms 23 and hence placed under tension when pressinj?r them flown over the seat-s 28, which occupy p0- sitions between the springs 30 and the arms Labels of any shape and of various sizes are readil)v introduced between the paperholdinxgY devices and platen and may be partially or entirely covered with writing as desired. the paper-holding lingers covering and holding the label on opposite sides of the printing point, but permitting the writing to he scanned, owing to the transparent materialen which the fingers are composed.

It Wili be seen that the paper is maintained against the platen at the shifting printing point, by the transparent spring actuated fingers which extend across the printing line on opposite sides of the rinting point, and are supported inde-pen ently of the platen and platen frame. The paper is held against the. platen at theprinting point noty only whether the latter is feeding as in'letter-spaciirgT and line-spacing, but also in case-shiftinel movements of the platen` the arrier constitutingr a shiftahle -apport avtuated by the platen shitting mechanism in printing upper or lower case "haraeteis.
